Buscando qualidade de código (parte 1)
Essa semana durante uma sessão de refatoração, tive a idéia de sempre que me deparar com situações de códigos que precisam ser alterados afim de se adequarem a alguns princípios de boas práticas de desenvolvimento de software, vou compartilhar aqui, explorando os pontos negativos do código e as vantagens de se adequar a um desses princípios, falando também um pouco sobre eles, um caso de cada vez, começando agora com OCP (Open-Closed Principle).
The Open-Closed Principle
Este princípio é a fundação para construção de códigos reutilizáveis e de fácil manutenção. Módulos que se adequam a este princípio são, ao mesmo tempo, abertos para serem extendidos, de maneira que se comporte de maneiras diferentes, a medida que surgem novos requisitos para a aplicação, ou a medida que estes são modificados. E fechados para modificação, o que significa que o código fonte deste módulo não pode ser violado, ninguém pode fazer mudanças neste código fonte.
A descrição deste princípio pode parecer conflitante, já que para extender a funcionalidade de um módulo, é necessário modificá-la, logo deduzimos que uma funcionalidade que não pode ser alterada é dada como fixa. Como este conflito pode ser resolvido? A melhor maneira de demonstrar é através de um exemplo.
No projeto CartolaFC, que estou trabalhando atualmente, existe um gerenciador de tarefas que é responsável pela execução assíncrona de tarefas enfileiradas pela aplicação. Basicamente ele percorre uma lista de pendencias, executando cada uma das tarefas, na ordem em que aparecem. O código abaixo está modificado em relação ao original, para podermos visualizar com mais facilidade.
public class GerenciadorDeTarefas {
public List<Tarefas> pendentes;
public void executaTarefasPendentes() {
for (int i=0; i<pendentes.length; i++) {
Tarefa tarefa = pendentes[i];
switch (tarefa.tipo()) {
case calculoTrofeus:
engine.calculaTrofeus();
break;
case calculoEstatisticas:
engine.calculaEstatisticas();
break;
}
case fechamentoDeMercado:
engine.fechaMercado();
break;
}
case aberturaDeMercado:
engine.abreMercado();
break;
}
// .... e assim continua ....
}
}
}
O método executaTarefasPendentes() não se adequa ao Open-Closed Principle, pois não está fechado para novos tipos de implementação. Se um dia o cliente decidir extender esta funcionalidade para incluir novas tarefas a serem executadas, que é o que acontece hoje em dia, o método terá que ser modificado para atender este requisito, incluindo mais um bloco “case”, que já não é nada elegante, e assim continuará, para cada novo tipo de tarefa.
O código, na vida real é ainda pior, atualmente são 18 blocos “case”, o que torna a implementação de novas tarefas uma prática intrusiva, suja e acoplada (imagine se todos os métodos a serem executados para as tarefas ficassem espalhados… quantos objetos teríamos que instânciar no gerenciador de tarefas…)
O código a seguir mostra a solução que pretendo dar para este problema, uma solução que se adequa ao Open-Closed Principle. Resumindo, a classe Tarefa se torna abstrata e acrescentamos a ela um método abstrato chamado executar(). Com esse approach, TODOS os tipos de tarefas criados, serão classes concretas que derivam desta classe, implementando seu método abstrato.
public class abstract Tarefa {
public abstract void executar();
}
public class CalculoDeTrofeus extends Tarefa {
public void executar() {
// lógica para cálculo de troféus...
}
}
public class CalculoDeEstatisticas extends Tarefa {
public void executar() {
// lógica para cálculo de estatísticas...
}
}
E a partir de agora, para o nosso gerenciador de tarefas, o ato de invocar as tarefas pendentes fica totalmente transparente. Tudo que ele precisa fazer é percorrê-las, e para cada uma, invocar seu método executar(), tornando o código não intrusivo, limpo e desacoplado.
public class GerenciadorDeTarefas {
public List<Tarefas> pendentes;
public void executaTarefasPendentes() {
for (int i=0; i<pendentes.length; i++) {
Tarefa tarefa = pendentes[i];
tarefa.executar();
}
}
}
Agora, se quisermos extender a funcionalidade de executarTarefasPendentes() do nosso gerenciador para que passe a executar uma tarefa nova qualquer, tudo o que precisamos fazer é adicionar uma nova implementação para a classe abstrata Tarefa. O nosso método executarTarefasPendentes() não precisa ser alterado, se adequando ao Open-Closed Principle. Seu comportamento pode ser extendido, sem que ele seja alterado.

Muito bom. São coisas simples como essa que fazem a diferença entre um sistema impossível de dar manutenção e um sistema orientado a objetos elegante.
September 20th, 2007 at 4:17 pm
Fora que agora você:
1) Eliminou a dependêndia entre quem coordena o trabalho de quem executa o trabalho com um Command
2) Pode colcoar as regras de negócio nos lugares corretos
Mais sobre este assunto na próxima Mundo .Net (sim, é jabá)
Mas já que estás falando nisso, que tal transformar essas coisas todas em Message-Driven Beans? Colocando numa fila JMS você tem de graça controle de rollback, mensagens perdidas, possibilidade de adicionar mais workers a qualquer momento…
September 21st, 2007 at 11:06 am
Sim, é uma das opções que venho pensando.
Quero evoluir com esta solução, pois existem casos que a execução de uma tarefa depende do término de uma outra e assim por diante.
Alguém conhece algo para esse tipo de controle? Ou tem que fazer na munheca mesmo?
September 24th, 2007 at 5:54 pm
Solução boa, e me pareceu que muito com o padrão Command.
September 26th, 2007 at 10:10 am
interessante… a aplicação de transferencia de PMA tem um trecho com alguns case do jeito que voce exemplificou… essaa solução dá uma melhorada no código.
September 27th, 2007 at 4:29 pm
Aê, mas pq a tarefa é classe abstrata e não interface? hein? mm? mmm?
September 27th, 2007 at 4:56 pm
Vanessa,
muito boa sua pergunta! Perguntas como esta sempre devem ser feitas no design de um sistema.
No exemplo do post não dei importância a essa diferença, queria uma classe que servisse como um contrato com quem extendesse/implementasse ela, desde que sejam classes concretas, a obrigação da implementação do método
executar().Mas o certo é que fosse uma interface, como diz o texto abaixo, retirado deste artigo da JavaWorld
